README

A Sphinx manual as an omnidocs manual, from its JSON builder's output (sphinx-build -b json docs out) and its objects.inv:

• a page per document, in the order the root document's toctrees give (each document's "next");
• Sphinx's HTML brought to omnidocs' conventions: admonitions (note, tip, hint, important, warning, caution, danger, seealso) are callouts, versionadded / versionchanged / deprecated carry their version, a highlighted block is a code frame (Pygments' colouring kept), the title is printed by the page, links between documents go to their pages, pictures to the linker, viewcode's [source] links, scripts and styles left out;
• the inventory's entries (py:function, py:class, py:method... - not its std: labels) are the API entries, at their anchors, with their signature and first sentence read in the page.

$manual = (new Omnidocs\Sphinx\SphinxSourceFactory())->create(['dir' => 'build/json', 'docs' => 'docs']);

Inventory::read('objects.inv') reads any Sphinx inventory of version 2 (intersphinx's format).

Verified, and not

• Verified (omnidocs' harness, PHP 8.4): omnidocs' conformance suite on Requests' documentation (psf/requests v2.32.3) built by Sphinx 8.1.3's JSON builder - six of its documents as fixtures, the whole output (15 documents, 167 API entries) with omnidocs real; BareTest.
• Not verified: other domains than Python's (cpp:, js:) beyond their names; themes' extra context; MyST (Markdown) projects; math (MathJax is a script, left out: formulas show as their source).
